I think iTunes is a piece of crap. My reasons are legion. One of the main ones is the sever use of DRM through the iTunes Store. There are ways around that, but it’s still a pain.
Likewise, if you rip a disc to your hard drive and don’t change any settings, the album is imported in an Apple-proprietary format, the AAC format. This is only useful so long as you stay with apple products. Again, not a friendly thing. You can get around this by setting iTunes to import using MP3 format.
But! Something I just learned. When you update the iTunes software, it automatically resets your setting back to AAC. So all those discs you’ve spent time ripping are in AAC rather than MP3, therefore entirely un-portable.
Bite me, Apple, inc. Bite me, Steve Jobs. You guys are not nearly all that.
